RESUMO

BACKGROUND: CCD presents as non-caseating granulomas within the skin at a site distant from the GI tract. CCD is a debilitating extraintestinal sequela of CD that can sometimes precede its GI manifestations. In the absence of GI symptoms, the histopathologic and clinical features of CCD can present as a variety of inflammatory skin conditions that can range from ruptured follicle-associated granulomas to cutaneous ulcerations. While a variety of therapeutic options for patients with CCD and concurrent luminal CD have been described in the literature, there is no standard treatment algorithm for the management of refractory CCD with limited or covert GI involvement. CASE REPORT: The authors discuss the case of a 33-year-old female who presented to the wound care clinic with multiple "knife-edged" cutaneous ulcerations involving the intertriginous spaces, found to be consistent with CCD. Her original cutaneous symptoms and diagnosis manifested with minimal GI involvement and responded to IVIG treatment. CONCLUSIONS: This case supports the inclusion of CCD in the differential diagnosis in patients with knife-edged granulomatous skin lesions in intertriginous locations. This clinical condition may present in the setting of no or limited GI symptoms. The management of CCD and a proposed treatment algorithm are also presented.

RESUMO

ABSTRACT: The comprehensive management of a patient with chronic graft-versus-host disease skin ulcers after hematopoietic stem cell transplantation is challenging. This report describes the case of a 53-year-old woman who presented with ulcers on her right leg 140 weeks after a bone marrow transplant. The patient received wound assessment and management based on the Triangle of Wound Assessment and Wound Bed Preparation 2021, respectively. Hydrogel and antibacterial protease dressings were applied along with systemic oral administration of moxifloxacin hydrochloride (two capsules, two times daily) and JiXueGanPian tablets (classic Chinese herbal formula; two capsules, two times daily), hospital-community-home continuous care, and patient-centered education. Finally, after 133 days of nursing, the patient's wound was completely healed without complications or other skin issues. The use of hydrogel combined with the antibacterial protease dressing was a promising technique for handling this type of wound, enhanced by multidisciplinary collaboration. Of course, providing patients with education that focuses on prevention is necessary.

RESUMO

OBJECTIVE: . Aim: The purpose of the study was to identify the features of apoptotic and proliferative processes in experimental Staphylococcus aureus-infected radiation skin ulcer under conditions of photodynamic therapy and the use of platelet-rich plasma. PATIENTS AND METHODS: Materials and Methods: An experimental study was conducted on 95 six-month-old male rats of the WAG population, which were divided into three groups. Group 1 included 25 animals that were simulated a radiation ulcer of the skin in the thigh area with subsequent application to its surface on the 7th day after irradiation with 0.2 ml of a suspension of the Staphylococcus aureus (ATCC 25923) reference strain (0.5 million microbial cells/cm2). Group 2 included 25 animals with Staphylococcus aureus-infected radiation skin ulcer, which were subjected to photodynamic therapy a day after infection. Group 3 included 45 animals with Staphylococcus aureus-infected radiation skin ulcers, which, 1 day after infection, received photodynamic therapy in the first half of the day, and in the second half of the day the periphery of the wound defect was injected with platelet-rich plasma. The material for the study was skin with underlying soft tissues from the area of radiation exposure. Histological, immunohistochemical, morphometric and statistical methods were used. RESULTS: Results: In cases of simultaneous use of photodynamic therapy and platelet-rich plasma, compared with photodynamic therapy alone, the processes ofapoptosis and proliferation were more balanced, active, with a shift in the proliferative-apoptotic ratio towards proliferation processes and met the needs of the regenerative process. From the 10th to the 22nd day of the experiment these processes increased, which indicated active healing processes, that, during survey microscopy on the 22nd day, were manifested by the complete filling of the wound cavity with granulation and connective tissues with the presence of an epithelial layer on the surface of the regenerate. From the 22nd to the 45th day of the experiment, a decrease in the rate of regeneration was recorded, as evidenced by a decrease in the intensity of apoptotic and proliferative processes. The intensity of the latter was sufficient, which led to the healing of Staphylococcus aureus-infected radiation skin ulcer on the 45th day with complete restoration of the original structure of the skin. CONCLUSION: Conclusions: Photodynamic therapy in combination with the use of platelet-rich plasma balancedly activates apoptotic and proliferative processes with a predominance of the latter in granulation and connective tissues filling the lumen of Staphylococcus aureus-infected radiation skin ulcer, which on the 45th day of the experiment leads to wound healing with complete restoration of the original structure of the skin.

RESUMO

Antimelanoma differentiation-associated protein 5 positive dermatomyositis (MDA5 DM) is a rare subtype of idiopathic inflammatory myopathy. There are limited data available regarding the cutaneous manifestations of MDA5 DM in the African American population. We presented the case of a male patient in his early 20s who presented with debilitating cutaneous ulceration and myopathy. Workup revealed interstitial lung disease (ILD) and positive MDA5 serology consistent with MDA5 DM. He made a remarkable recovery in terms of myopathy and cutaneous ulcerations with a multipronged regimen of prednisone, intravenous immunoglobulin and mycophenolate mofetil. However, there was a progression of ILD on this regimen which warranted use of rituximab.

RESUMO

Calciphylaxis is a rare and devastating condition found almost exclusively in patients with end-stage renal disease. Nonuremic calciphylaxis, an even more rare diagnosis, occurs in patients with preserved kidney function. We present a fatal case of nonuremic calciphylaxis with delayed and unexpected diagnosis despite early biopsy and testing. The patient presented with a 2-month history of painful ulceration to the left leg. Early biopsy was negative for calciphylaxis. Laboratory tests were negative for renal disease and autoimmune disorders. There was elevated parathyroid hormone (96 pg/mL) 3 months after initial presentation and documented cobalamin deficiency. The patient went on to develop wounds to both legs and her thighs. A second biopsy of a left thigh wound by means of the dermatology service revealed calciphylaxis. The purpose of this case report is to raise awareness of calciphylaxis as a differential diagnosis for chronic necrotic skin ulcers, especially in patients with preserved renal function and those on warfarin therapy.

RESUMO

Chronic skin wounds represent a prominent etiological factor in the occurrence of non-traumatic foot amputations on a global scale and pose a substantial threat to the patient's well-being and mortality in the absence of effective treatment strategies. There exists a subset of patients that exhibit an insufficient response to different treatment options, comprising antibiotics, dressings, gauze bandages, debridement, rehabilitation, collagen patch, and vacuum-assisted closure. In this patient group, distinct treatment strategies emerge before surgery and amputation. Ozone therapy is one of them. Ozone exhibits a wide variety of effects such as antimicrobial, anti-inflammatory, antioxidant, and trophic. Its trophic effect is mediated by disinfection, stimulation of granulation tissue, acceleration of the angiogenesis process, and detoxification mechanisms. In this article, we presented the beneficial effect of ozone therapy in a case of chronic skin ulcer associated with livedoid vasculopathy. In this context, we aimed to discuss the role of ozone therapy in the management of chronic skin ulcers. Finally, we focused on ozone therapy as a promising method in inflammatory rheumatic diseases.

RESUMO

This report presents the case of an 11-year-old girl with juvenile dermatomyositis (JDM), anti-MDA5 antibodies and multiple skin ulcers. Treatment with traditional immunomodulators and tofacitinib resulted in healing of the skin ulcers and normalization of muscle enzyme markers. This case highlights the significance of recognizing the association between anti-MDA5 antibodies and cutaneous ulceration in JDM and supports the use of Janus kinase inhibitors as a management option.

RESUMO

Marjolin's ulcer is described as malignant lesions developed in the injured skin, which can cause several kinds of malignancies. Our results showed that no HER2 but p53 was detected in Majorlin's ulcer samples. Meanwhile, by statistical analysis, we found that the positive rate of p53 in Majorlin's ulcer samples was associated with the pathological type of ulcer canceration and degree of tumor differentiation. The positive expression rate of vascular endothelial growth factor (VEGF) was 62.5% in poorly differentiated squamous cell carcinoma (SCC), 39.4% in moderately differentiated SCC, and 66.7% in well-differentiated SCC, respectively. Furthermore, some cases of Majorlin's ulcer with positive P53 were negative for VEGF, while some cases with positive VEGF were negative for P53. Image superposition showed that VEGF expression was absent or minimal in p53-positive cases. However, P53 was not expressed or rarely expressed in VEGF-positive cases. Our results of this study will suggest that P53 can be used as the mark of Marjolin's ulcer differentiation, and there may be some interaction between P53 and VEGF in Marjolin's ulcer. The regulation of microenvironment in the oncogenesis, progression, and differentiation of Marjolin's ulcer is complex and needs further study.

RESUMO

BACKGROUND: There is a strong rationale to develop locally-acting surgical treatments for digital ulcers (DUs) in patients with systemic sclerosis (SSc). Our aim was to examine the safety and efficacy of local surgical management for SSc-DU. METHODS: A systematic literature review was carried out until to August 2022 using 7 different databases. Original research studies concerning adult patients with SSc-DUs, and local surgical treatments were analysed using the PICO framework. We included randomized controlled trials, prospective/retrospective studies, and case series (minimum of 3 patients) References were independently screened by two reviewers including assessment of the risk of bias using validated tools. RESULTS: Out of 899, 13eligible articles were included. Autologous fat (adipose tissue AT) grafting was the surgical modality most identified (7 studies, 1 randomized controlled double blinded trial and 6 prospective open-label single arm studies). The healing rate (HR) with autologous fat grafting (4 studies) was 66-100 %. Three studies reported autologous adipose-derived stromal vascular fraction grafting: HR of 32-60 %. Bone marrow derived cell transplantation in a single study showed 100 % healing rate over 4-24 weeks. Surgical sympathectomy was examined in 3 studies, prospective without comparator with a median healing rate of 81 %. Two surgical studies (of direct microsurgical revascularisation and microsurgical arteriolysis) showed 100 % healing of ulcers, with no complications. CONCLUSION: Several surgical approaches for SSc-DUs have demonstrated some degree of safety and effectiveness for DU healing. However, there are significant methodological issues. Future studies are warranted to rigorously investigate surgical interventions for SSc-DUs.

RESUMO

Background: Marjolin's ulcer is the malignant degeneration of any chronic wound, with a latency period from tissue injury to variable malignant transformation that may occur up to 30 years later. Among the associated neoplasms, squamous cell carcinoma (SCC) is the predominant lineage in up to 71% of cases. The verrucous carcinoma variant has been estimated to have a low presentation, being described in the literature as 2% of all SCC and reported anecdotally in immunosuppressed patients, which justifies the objective of this publication. Clinical case: 65-year-old female patient with a history of being a carrier of human immunodeficiency virus (HIV) infection, who presented a verrucous carcinoma associated to a Marjolin ulcer secondary to herpes zoster and infection of soft tissues in the right leg, with a latency period of 10 years from the initial infectious process to histopathological confirmation. Conclusions: The finding of a verrucous carcinoma on a Marjolin ulcer has been little described in literature, with a lower incidence in the context of a patient with a history of being a carrier of HIV infection, finding 7 case reports, the oldest from 1998. For this reason, it is important to have diagnostic suspicion, to carry out an adequate study protocol and always making clinical-pathological correlation, in order to establish timely and individualized treatment.


Introducción: la úlcera de Marjolin es la degeneración maligna de cualquier herida crónica, con un periodo de latencia desde la lesión tisular a la transformación maligna variable que puede presentarse hasta 30 años después. De las neoplasias asociadas, el carcinoma espinocelular es la estirpe predominante hasta en 71% de los casos. La variante de carcinoma verrugoso se ha estimado con una presentación baja, pues ha sido descrito en la literatura como el 2% de todos los carcinomas espinocelulares y reportado de manera anecdótica en pacientes inmunosuprimidos, lo que justifica el objetivo de esta publicación. Caso clínico: mujer de 65 años con el antecedente de ser portadora de infección por virus de inmunodeficiencia humana (VIH), que presentó un carcinoma verrugoso asociado a una úlcera de Marjolin secundaria a herpes zóster e infección de tejidos blandos en pierna derecha, con un periodo de latencia de 10 años desde el proceso infeccioso inicial hasta la confirmación histopatológica. Conclusiones: el hallazgo de un carcinoma verrugoso asentado sobre una úlcera de Marjolin ha sido poco descrito en la literatura, con una menor incidencia en el contexto de un paciente con antecedente de ser portador de infección por VIH, ante lo cual encontramos 7 reportes de caso, el más antiguo de 1998. Por este motivo es importante contar con la sospecha diagnóstica, para poder hacer un protocolo de estudio adecuado y siempre haciendo correlación clínico-patológica, con la finalidad de instaurar un tratamiento oportuno e individualizado.

RESUMO

Cutaneous malignant melanomas of the head and neck (HNM) are proposed to have notable histological and clinical differences from those at other sites (other melanoma); however, HNMs among Asians have remained poorly understood. This study aimed to investigate the clinicopathological features and prognostic factors of HNM in Asians. Asian melanoma patients who underwent surgical treatment from January 2003 to December 2020 were retrospectively reviewed. The clinicopathological features and risk factors for local recurrence, lymph node metastasis, and distant metastasis were analyzed. Among 230 patients, 28 (12.2%) were diagnosed with HNM, and 202 (87.8%) with other melanoma. The histologic subtype significantly differed as the nodular type was predominant in HNM whereas the acral lentiginous type was predominant in other melanoma ( P  < 0.001). HNM was significantly associated with higher local recurrence ( P  = 0.045), lymph node metastasis ( P  = 0.048), distant metastasis ( P  = 0.023), and lower 5-year disease-free survival ( P  = 0.022) than other melanoma. Ulceration was the risk factor for lymph node metastasis based on multivariable analysis ( P  = 0.013). A high proportion of HNM present as the nodular subtype in Asians, leading to poor outcomes and low survival. Therefore, more cautious surveillance, evaluation, and aggressive treatment are required.

RESUMO

RATIONALE: Metaplastic breast cancer (MBC) is a rare tumor of the breast, and skin ulceration of breast tumors is a difficult clinical problem that reduces the patient's quality of life. PATIENT CONCERNS: There are currently no Standard Treatment Guidelines for MBC at present, and the treatment for the skin ulceration of breast tumors is limited in clinics. DIAGNOSIS: Here, we report the case of a patient with a large MBC and skin ulceration, accompanied by exudation and odor. INTERVENTION: The combined treatment of albumin paclitaxel and carrelizumab (anti-PD-1 immunotherapy) was effective in reducing the tumor, but it increased the severity of the skin ulceration. After taking traditional Chinese medicine, the skin ulceration healed completely. Then the patient underwent a mastectomy and radiotherapy. OUTCOMES: The patient has a high quality of life and was in good condition after the comprehensive treatment. LESSONS: This suggests that traditional Chinese medicine may have a good auxiliary therapeutic effect on the skin ulceration of MBC.

RESUMO

Trigeminal trophic syndrome (TTS) is an uncommon and relatively unknown cause of facial ulceration that occurs after damage to the trigeminal nerve. It characteristically involves non-healing facial ulceration(s) with accompanying anesthesia, paresthesia, and dysesthesia along the distribution of a trigeminal dermatome. The ulcerations are believed to be self-induced in response to paresthesia. The disease is most common in middle-aged women, manifesting as a unilateral crescent-shaped ulceration on the ala nasi, with sparing of the nasal tip. The diagnosis is clinical and mostly based on exclusion of other possible causes of facial ulcerations, with emphasis on neoplasms, infection-associated vasculitis, and factitial disorders. There are no specific histological or laboratory signs. There is no standard treatment protocol; however, a number of different successful strategies have been reported, including pharmaceutical and surgical interventions, transcutaneous nerve stimulation, and simple occlusion dressings. Due to the self-inflicted nature of this disorder, the cornerstone of management is patient education with behavioral modification. Here, we report a case of TTS following herpes zoster ophthalmicus and review the current literature on this subject.

RESUMO

Background: Granulomatosis with polyangiitis (GPA) is an antineutrophil-cytoplasmic-antibody (ANCA)-associated small-vessel vasculitis characterized by necrotizing granulomatous inflammation. Symptoms of skin involvement can appear in 30-50% of patients with GPA, and may present as the initial presentation. Case Presentation: We describe two patients who presented with multiple deep, large, nonhealing skin ulcers postoperatively with purulent drainage and fever. Both patients were diagnosed with GPA after an extensive evaluation, including histopathology. Infectious, connective tissue disease and malignant etiologies were excluded. Their cANCA and PR3-ANCA levels were positive. Patient 2 was diagnosed early and recovered well after treatment with corticosteroids and rituximab; however, Patient 1 had a poor prognosis due to a long disease course. Conclusions: Diseases with multiple deep, large skin ulcers and fever can be infectious or noninfectious. Atypical manifestations may lead to missed diagnosis and misdiagnosis. GPA may initially present in a localized form before progressing to a generalized disease. The two cases we have highlighted will prompt clinicians to nevertheless call for a low threshold for diagnosis.

RESUMO

RATIONALE: Marjolin's ulcer (MU) is a rare skin malignancy derived from a chronic wound. Pressure ulcer related MU possesses poor prognosis and high metastatic rate, and it is difficult to be differentiated, especially when superimposed infection. PATIENT CONCERNS: Here we report a case with pressure ulcer related MU which presented as necrotizing soft tissue infection (NSTI) to demonstrate the manifestation, treatment, and prognosis of this rare disease. DIAGNOSES: A 45-year-old male patient had spinal cord injury at age 2 years. He presented ischial pressure sore complicated with NSTI initially. After serial debridements and antibiotic treatment, the infection subsided. For the persistent verruca-like skin lesion, he underwent wide excision which revealed well-differentiated squamous cell carcinoma. Further image studies showed localized residual tumor without distant metastasis. INTERVENTIONS: He then underwent hip disarticulation and anterior thigh fillet flap reconstruction. Local recurrence developed 3 months later, and re-wide excision and inguinal lymph node dissection were performed. No lymph node metastasis was noted and adjuvant radiotherapy was given. OUTCOMES: He was followed for 34 months and no recurrence or metastasis was found. The patient can move with a wheelchair or a hip prosthesis, and is partially dependent for daily activities. LESSONS: MU can masquerade as NSTI and one should be alert to its malignant potential. Due to its aggressive nature, limb sacrifice can be considered in circumstances of profound involvement. As for the reconstruction method, pedicled fillet flap provided good wound coverage.

RESUMO

A 13-year-old girl with a history of diffuse intrinsic pontine glioma (DIPG) suffered from progressively worsening facial ulcerations secondary to paresthesia-induced self-excoriation. She was diagnosed with trigeminal trophic syndrome (TTS) induced by DIPG and struggled to heal her lesions in the background of this excoriation disorder. A multidisciplinary approach that included mood disorder management with sertraline and amitriptyline helped diminish paresthesia, improve her quality of life, and promote healing of the ulcers despite the progression of her DIPG. This case highlights the multifactorial complexity of TTS in pediatric patients and the need for successful management strategies.

RESUMO

OBJECTIVE: Tissue hypoxia due to microvasculopathy is the main cause of digital ulcers (DUs) in systemic sclerosis (SSc). Reduced oxygen delivery (DO2) to the tissues may also contribute to the development of DU. This study was conducted to investigate the association between DO2 and DUs in patients with SSc. METHODS: In all, 111 patients and 30 healthy controls were enrolled. DO2 was calculated by using the formula; DO2 = Cardiac output × arterial oxygen saturation (SpO2) × serum haemoglobin level × 1.39 × 10. Both right index finger SpO2 measurements (index-SpO2) and highest value of SpO2 (maximum SpO2) obtained among the fingers of the subjects were used for the calculations and DO2 results were adjusted both for weight and body surface area (BSA). RESULTS: Mean DO2 was lower in SSc patients as compared to controls in all 4 different calculations but the difference was only statistically significant when using index-SpO2 and adjusting for BSA (498 mL/min/m2 vs 549 mL/min/m2, p = 0.03). There was a strong positive correlation between cardiac output and DO2 calculated by using the index-SpO2 (r = 0.903; p < 0.001). Of the SSc patients, 46 (41.4 %) had DUs within the last 12 months. Patients with DUs had higher mean mRSS, lover mean FVC and more frequently diffuse disease, interstitial lung disease, anti-SCL70 antibody positivity (p < 0.05 for all). No difference was observed in DO2 among DU positive or DU negative groups by any calculation (p > 0.05 for all). CONCLUSIONS: DO2 in SSc patients seems to be lower than healthy controls. However, DO2 is similar between the patients with and without DUs. Our results suggest that the contribution of DO2 is negligible to the development of DU and support the major role of microvasculopathy in SSc patients with DUs.
